I believe that these are still available from Year One. Anybody know anything about these? Were they ever installed on any of the SS models? Gains? I assume they would not add as much as shorty headers, but they are much cheaper, especially if you are going w/ ceramic coated.

Dont wast your time and money on those.If you want performance get headers.

What joe said.....complete waste of money and time putting them in. A set of 1 5/8th or 1 3/4 shorties or LTs would make alot more power...

I believe these were stock manifolds that were extruded honed. Like said not much gain, just that all the casting rough spots were smoothed out, maybe 5-10 hp.

This has been asked before, and the answer remains the same
If you have ever did headers, you'd feel really dumb to pull the manifolds and replace them with manifolds. I would put headers in if they didn't raise Horse power just because I can change my plugs in 30 minutes.

No cuts or bruises here, plus wires changes are a snap with a good OTVC setup!
